Weeks into staying home from preschool, Betty, 4, threw herself on the floor and had a screaming meltdown. She had had a Zoom meeting with her class earlier that day, and every little thing was setting her off. “We don’t accept screaming in our house,” said Betty’s mother, Laura Bower-Phipps, professor and coordinator of elementary education at Southern Connecticut State University in New Haven. “So, we counted the screams, and when she hit three, my wife and I told her she needed to take a break for four minutes.” Betty took the break, came back and screamed three more times, and again went to her quiet spot for another four minutes. And so, it went on.
